These include a test of the standard model using isospin sum rule, an investigation of localized $\CP$ asymmetries in the Dalitz plot, and an expected improvement on the precision of the CKM unitarity angle $\phi_{2}/\alpha$. All the results agree with the previous determinations and contribute important information to an early assessment of Belle~II performance. 000002944 8560_ $$fsagar.hazra@tifr.res.in 000002944 8564_ $$uhttps://docs.belle2.org/record/2944/files/BELLE2-CONF-PROC-2022-009_final.pdf
